Mapped drive not showing as an available folder

I actually don't even know how to properly phrase this question, but I currently have my Synology drive mapped through tailscale for remote access.

I am able to see and access the mapped Synology drive through the file explorer window, but when I try to run a program that needs to access a folder the mapped Synoogy drive, it is not available or accessible.

I understand that it might be the program itself not allowing for the accessibility, so I suppose my question then is what can I do to somehow have a folder on my mapped Synology drive so that the program can access it?

The only thing that I have tried that kind of works is creating a synced folder to my computer and accessing it that way. However, the folder is ~80GB and has large files that are constantly being updated, so at the sync speeds (~1-2MB/s), it isn't practical.
